NVENTOR M a MMMM ATIORNEY '80 the disadvohtegcs is that it is rather tedious lliitent cil i iii,

Efiitiitllii "WEHDHG" heetioh Element-liven '3 Broaluct, or into suitable hells or packages.-

urizig. the reclin the yarh often breaks the operotoe to lmot together the broken ends. In unwinding the yarn from the core it is likely tocetch in'these knots and tfti". This danger exists particularly in the case of silk, artificial silk, or othec fine anti fro gile yarns. In order to prevent the yorn from catching on knots, it has been the prec this to Wind the yarn on s. cone-shaped core and. to place all knots at one end oi. the core in such a manner that all the knots the top this method reciuccs hreskogge during Winding, it has severel drawbacks. time i and thereiore expensive to locate the knots in the end stratum. Further trouiz-le erisce from the foot that when, after the tying ot a knot the winding operation is continued, the knot is likely to slip into it lower stratum and form an obstacle in the unrcclihg oi? the yarn.

It is the object of the present ihventioh to overcome these drawbacks by producing ii. 4 package of yarn preferably, but not necesszu'ily, in the form of yarn wound on e cone shaped core in which the knots may he deli.

nitely located in a level below that of yarn sections likely to catch in such knots, i. e.., yarn sections located in the some or adjacent layers.

In accordance with the preferred emheoliment of the invention herein disclosed this is accomplished by producing a Winding), of

yarn in each layer of which certoiri sections of the yarn are below the general level of the layer, e. g., by producing a. groove intermediate the ends of the. Winding.

and it is necessary for c. cone of yorn provided with a.

or bottom stratum of the Winding.

The 'Wiiiciing; operation may then continue "WltiIO'Uh of the 111M053 slipping out oi the groove 3, as would he the case is the knot were placed on the top or bottom stotnm (atijccent the apex or tee of cone 2) of the yarn.

finch groove 3 mm; he formed in the leycr, oi yarn on core 2 y using a pointed ilk-W5 strumcnt t which is pressed towards the'coho 2- 'while yarn" is being woimththereoh. As the yarn is passed back end. forth during its winding on the cone 2, when it passes under the tool 4 it will he flattened or prcsscci more tightly, and in the ultimate product it depression or groove will he found at the point where the tool bore against the yarn.

in applying the ing machines such tool to well-known winch we as the one mahutactorcci to form ofa pointer provided with a longitudinal slot and mounted by means of a bolt 6 projecting through said slot on an arm 7;. By means of a bolt'8 the yarn. 7 is slidablymounted on one'lcg of a il shaped -hracketx9, theother leg of which is pro vided with projections 10 and 11, by means at which it may be attached to the winding machine. By means of the bolts 5 and 8, the attachment maybeadjusted for various sizes of yarns and cones and degrees of tension.

As shown in Fig. 1 the attachment is fastened to afplatform 12 by. means of set screws like 13. The platform 12 may be reciprocated with respect to head 14 on which a. paper cone 2 may be clamped under the control of a lever 15, The platform 12 swings around a shatt.16 and is normally pressed towards the cone 2 by means of a weight 17 and suitable tensioning spring 18s The shaft 19 is rotated by a suitable motor drive (not shown) and causes the rotation of cone 2. The yarn 1 passes be; tween the legs of the bracket 9 onto the cone at the required tension and suitable way or guarding against this means (not shown) are provided for equally vdistributing'the yarn to form a layer of required width on the cone.

The end of pointer 4 must, of course, not bear against the yarn so as to injure it, @no is by round ing the end of the pointer. Another way of protecting the yarn against injury shown in Fig. 4 in which a roller 20 mounted on a pin 21 provided at the end ct pointer 4. This roller may be made'cf perceain or glass with rounded edges and should be freely rotatable aroundthe pin 21. The

width of the roller 20 will width of groove 3.

What I claim is:

. 1.. As a new article of manufacture, a yarn winding in which in each layer certain determine the portions of the yarn are below the general level of the layer, the lowered portions at fording a depression within which knots are placed.

2. As a. new article of manufacture, a yarn windiughaving layers in which certain sections of the yarn are below the general level of the layer, the lowered sections afi'ortL ing a depression within which knots are placed 3 As a new article 01; manufacture, a grooved winding of yarn with the knots located in the groove.

4. As a new article of manufacture, a cone of yarn having a groove within which the knots are confined.

5. As a new article of manufacture, a cone of yarn having a groove at right angles to its axis and intermediate its ends, the knots in the yarn being confined in the groove.

6. The method of winding yarn on a core which consists in bearing with a tool against the core durin the winding of the yarn thereon to produce a groove in each layer of yarn, and placing the knots by which yarn ends are fastened together within-the confines of said groove.

In testimony whereof, I have signed my name to this specification, this 4th day of September 1 25.
